Patented Feb. 4, 1908.

T o all whom 'it may concern:

Be it known that l, ADOLPH L. GLAENTZER, of New York, in the count-y of New York and in the State of NewYork, have invented a ce1'- tain new and useful Improvement in Lamps, and do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, in Which- Figures 1 and 2- are vertical sectional views of a lamp embodying my invention, the parts being shown in di'erent positions; Fig. 3 is a view of my combined chimney and mantle carrier removed from the lamp Figs. 4 and 5 are, respectively, a side elevation and a vertical sectional view of my gas-regulator; Figs. 6, 7 and 8 are detail plan views of parts of such regulator; and, Fig. 9 is a side view of another embodiment of my regulator.

The object of my invention has been to rovide a lamp having a mantle, which shall have an improved gas regulator. that shall offer the least possible resistance to the :[low

of the gas; and which shall have an improved mixing chamber, in which the gas shall be thoroughly mixed and that shall have a combined removable chimney and mantle carrier, and especially one that is supported solely by the gas supply pipe, and to such ends, my invention. consists in the lamp hereinafter specified.

The broad subject-matter of a combined removable chimney and mantle carrier is claimed in a companion case Vfiled of even date herewith, to which case reference is made for a full statement of the advantages of such a carrier.

In carrying` my invention into practice, I have chosen for illustration a street lamp, but my invention and the various features thereof are equally applicable to other forms of lamp, whether having one or a plurality of burners. The lamp casing A may be of any desired construction, and l will, therefore, not describe the casing l have illustrated further than to say that access is had to its interior by a hinged cover B; but my invention is equally applicable to all other forms of casing, such, for instance, as one having a side door. The usual gas pipe C enters the casing from the lamp post D, and such pipe is provided with a branch pipe c, as by a tee, and at the union of such branch and main pi es is a gas cock c having a bypass to supp y gas during the iirst part of its opening movement to the branch pipe.

Above the cock is attached, in any suitable manner, the base E of my gas regulator. The said base E has a larger cylindrical portion e rising therefrom and is exteriorly threaded to engage a tube F that leads to the mixing chamber. A smaller cylindrical portion e2 rises from the portion e', and is exteriorly threaded to receive a regulating cap or cone e3, said cap being sulllciently small to be received within the tube F and to be free to move therein. The tube F is cutaway to permit a pin e'1 on the cap to extend outside the tube so that it can be reached for manipulation. lf desired, the cap e3 can be knurled, and the tube F can be cut away on opposite sides, as illustrated in Fig. 5, so that the cap can be turned by the thumb and linger. A point e5 rises from the cylindrical portion e2, being supported therefrom by legs e, so that comparatively large openings c7 are formed at the base of the point. The point e5 is preferably tapered on the end, and is adapted to enter and close a hole es in the cap when the latter is screwed sufliciently down. The arrangement of my regulator is suoli that the gas passes unobstructed to the base of the point or to the top of the cylindrical portion e2, so that practically the full pressure of the gas arrives at the opening e7 in the cone, where the regulation actually takes place. ln all other regulators, with u hich l am familiar, the construction is such that the gas is choked down in the regulator, and does not reach the opening where the regulation actually takes place at its full pressure.

The branch pipe c extends upward, preferably vertically, and at its upper end is provided with a hollow socket G, the said pipe being open to the gas up to a point at least as high as the burner of the lamp and being closed below the socket to prevent escape'of gas through the socket. A series of small perforations is formed in the pipe c winding from a point on the outer side of the tube near its lower end to a point on the side of the tube toward the burner to form a climber light, so that thc cock on being partly opened will allow gas to pass into the branch pipo, as well as to the burner, to cause the flame of a torch applied at lower end of, the climber light to be carried along the line of perforations and communicated to the burner. A combined chimney, mantle holder and carrier is supported from the socket G by a rod H that is received in said socket, said rod being connected to the side, or other convenient portion, of a chimney I, so as to support said chimney in proper position. A pin h projects from the side of the rod H, and serves to engage an L-shaped slot g in the socket G to fasten the rod in the socket, the pin joint thus formed being a bayonet joint.

The chimney I has guides i formed inside it, in which guides is mounted a slide K, formed, in the present instance, in the form of a bail or handle 7c having two parallel wires 7c extending through the guides 'i in the chimney and supporting at their lower ends the lower chimney section L. A latch M, or other convenient form of fastening, is secured to the slide K, at any desired point such as to one of the wires 7f3, so that the said slide can be fastened in an upper position to hold the lower chimney section against the bottom of the chimney I. Supported within the lower chimney section L is a mixing chamber N. The said mixing chamber has a flaring tube fn, at its lower end, which tube is adapted to iit over and to receive the upper end of the tube F when, and only when, the pin h is in the horizontal part of the slot g, in which position the rod H is locked in the socket G against vertical movement, and the height of the tube F is such, relative to the range of movement of the tube n, that when the tube n is over the upper end of the tube F, the rod H cannot be turned in the socket G to bring the pin h beneath the vertical art' of the slot i (so that the chimney can be ifted up to take the rod H out of its socket) until the slide has been raised to lift the tube 'It above the tube F, and when the said slide has been so raised, the lower chimney section will be latched against the upper chimney section, and the mantle will be entirely inclosed and protected. The tube 'n connects with the lower part of the mixing chamber 'n' proper, which latter is much larger in diameter than the tube fn. Above the enlarged or mixing chamber proper n, there is a contracted or smaller tube 'n2 within the enlargement, and through such tube n2 the air and gas pass to the ignition point, there being at such point, preferably, the usual gauze O held by a shell 0, which shell is, as usual, provided with a mantle holder P supporting a mantle The shell 0 is supported on a spring 0 to prevent communicating jars to the mantle. rlhe gas and air, the latter entering the openings in the sides of the tube F, pass upward through the tube F, and by first passing into the enlarged portion of the mixing chamber, and then passing into the contracted portion thereof, are thoroughly mixed, the mixture being much more effective than if the mixing chamber were of uniform diameter. rThe air and gas, in seeking to pass through the smaller tube n2 are agitated, and currents of air are set up, so that the mixture becomes much more complete than if said contracted tube were in use.

It is obvious that the construction herein described has great advantages. Being independent of the form of lamp casing, it can be applied to lamps already in use.

'Being entirely supported from the gas pipe,

if, as is the case in a high wind, the lamp post sways, there will be much less tendency for the gas pipe and the burner to sway, since the wind does not reach the pipe, the burner, nor any of their attached parts.

The carrier cannot be disconnected and removed without first inclosing and protecting the mantle. The spring support of the mantle holder helps to prevent the breaking of the mantle by the rumbling of heavy vehicles over rough pavements nearby.

It is obvious that changes can be made in the above-illustrated construction whichwill be within the scope of my invention.

Having thus described my invention, what I claim is 1. In a lamp having a mantle, the combination of a chimney having means for supporting the mantle, a support directly connected to the gas pipe, and means for removably attaching said chimney to said support.

2. In a lamp having a mantle, the combination of a chimney having meansfor supporting the mantle, and having a normally downwardly projecting rod attached thereto, and an upwardly opening socket connected to the lower part of `the lamp and in which said rod is adapted to be received.

3. In a lamp having a burner and mantle, the combination of a chimney having means for supporting the mantle, and having a normally downwardly projecting rod attached thereto, an upwardly opening socket in which said rod is adapted to be received, and a pin on said rod engaging an L-shaped slot in said socket to secure such parts together.

4. In a lamp having a mantle, the combination of a chimney having a mantle and having a rod secured thereto parallel to the chimney, a vertical socket attached to the fixed parts of the lamp, a pin on said rod and an L-shaped slot in said socket to secure said parts together, a tube extending vertically upward from the gas cock, a slide on said chimney carrying a lower'chimney section, and a mixing chamber -in said lower chimney section, said mixing chamber having a tube extending downward therefrom, the vertical portion of said L-shaped slot being so positioned that said pin will only be in line therewith when said tube depending from said mixing chamber is in line with said tube extending upward from said cock.

5. In a lamp having a mantle, the combination of a chimney having a mantle and having a rod secured thereto parallel to the chimney, a vertical socket attached to the fixed parts of the lamp, a pin on said rod and an L-shaped slot in said socket to secure said parts together, a tube extending vertically upward from the gas cock, a slide on said chimney carrying a lower chimney section, a mixing chamber in said lower chimney section, said mixing chamber having a tube extending downward therefrom, the vertical portion of said L-shaped slot being so positioned that said pin will only be in line therewith when said tube depending from said mixing chamber is in line with said tube extending upward from said cook, there being a latch on said slide, said latch being so positioned as to catch on said chimney when the lower chimney section is against the lower end of the chimney.

6. In a lamp having a mantle, the combination of a cock adapted to be secured on a gas pipe, a burner, a chimney support, a chimney and a mantle holder, all connected to`said cock whereby said parts may be secured in said lamp or removed therefrom by connecting or disconnecting a single joint, said chimney support having a gas passage formed therein, which passage communicates with a by-pass in said cock, and said support having a transverse line of holes, extending to a point near said mantle, whereby said lamp can be lighted by a flame applied near the lower end ol5 said support.

In testimony that I claim the foregoing I have hereunto set my hand.
